Maintenance
Disassembly
Disassembly should be done on a clean workbench with a clean
cloth spread to prevent the loss of small parts. After disassembly
is completed, all parts should be thoroughly washed in a clean
solvent, blown dry with air and inspected for wear levels, abuse
and contamination. Double sealed or shielded bearings should
never be placed in solvent unless a good method of lubricating
the bearing is available. Open bearings may be washed but
should not be allowed to spin while being blown dry.
Disassembly:
1. Drive Gearing - Using wrenches on the ats of the
Ring Gear (40) and on the ats of the Housing Adapter (32),
unthread and remove Gear Assembly (36) from motor. Tap drive
end of Ring Gear (40) with a soft face hammer. Spindle (37) and
components will now loosen from Ring Gear.
Note: Do not disassemble further unless damage is evident. To
disassemble, remove Spacers (41 and 42). Alternately tap shafts (42)
to remove Bearing.
2. Auxiliary Gearing - Remove Drive Gearing. Loosen Lock Nut (47)
and unthread then remove Gearing Assembly (28) from Motor.
Tap splined end of Spindle (35) with a soft face hammer. Spindle
and components will now loosen from Housing Adapter (32).
Remove Bearing (29) from splined end of Spindle. Rotate Retainer
Ring (34), allowing removal of shafts and gears. Place shafts (42) in
Spindle and alternately tap ends of shafts, loosening Bearing (29)
from Spindle (37).
3. Motor - The Motor Assembly may be removed from Housing (27)
after the removal of Gearing or Head. Remove Retaining Nut (12)
and Screw (16). Grasp Cylinder (19) in one hand and tap splined
end of Rotor (21) with a soft face hammer. The Motor should now
begin to come apart.
4. Head - Remove Nut (10) to allow removal of Valve components.
Assembly
Upon reassembling, lubricate parts where required. Use
Ingersoll Rand #33153 grease, or equivalent, in Bearings. Use
#36460 lubricant for O-Ring assembly. When assembling O-Rings
or parts adjacent O-Rings, care must be exercised to prevent
damage to the rubber sealing surfaces. A small amount of grease
will usually hold steel balls and other small parts in place while
assembling.
Assembly:
1. Head - Grease and assemble O-Ring (6). Assemble Valve
Stem (5), Spring (7), Regulator (8), and Seal (9) into Valve opening
and secure with Nut (10).
2. Motor - Assemble Bearing (13) to End Plate (14), while pressing on
outer race of Bearing.
Note: Assemble with bearing markings facing outward.
Assemble Spacer (15) and End Plate (14) to Rotor (21) while
pressing on outer race of Bearing. Secure with Fastener (16), while
tightening to 28 in-lbs (3.2 Nm). Coat Rotor Blades with 29665
spindle oil and assemble in Rotor slots, with straight side facing
outward. Coat inner diameter of Cylinder (18) with 29665 spindle
oil and assemble to End Plate (14), while aligning Roll Pin (20) with
hole in End Plate and air inlets of Cylinder and End Plate.
Assemble Bearing (22) to End Plate (23), while pressing on outer
race of Bearing. Assemble End Plate to Cylinder while pressing
on inner race of Bearing. Assemble Retaining Nut (12) to End
Plate and torque to 9-12 ft-lbs (12-16 Nm). Be sure Rotor does not
bind and assemble to Housing. Assemble Spacers (48 and 49) to
Housing.
3. Auxiliary Gearing - Pack Bearings and lubricate gears liberally
with Ingersoll Rand #33153 grease when assembling. Assemble
Planet Gears (44) and Shafts (45) to spindle (37), aligning notch
in Shafts with Retainer Ring (30). Rotate open portion of Retainer
Ring 90° from Shafts, while securing Shafts in place. Assemble
Bearings (29) to Spindle. Assemble Retainer Ring (34) and Spindle
to Housing Adapter (31). Assemble Housing Adapter to Motor and
secure with Lock Nut (47).
4. Drive Gearing - Pack Bearings and lubricate gears liberally with
Ingersoll Rand #33153 grease when assembling. Assemble
Gears (44) and Shafts (45) to Spindle, aligning notch in Shafts with
Spacer (41). Assemble Spacer (46) and Bearing (29) to Spindle.
Assemble Spacer (42) to Spindle and assemble Spindle to
Ring Gear. Assemble Ring Gear to Motor.
Parts and Maintenance
When the life of the Motor has expired, it is recommended that the Motor be disassembled, degreased and parts be separated by material so
that they can be recycled.
